what is a high temperature

I ride a 2004 WR450F, and I was wondering what a high engine temperature is for this machine or one like it, right now I'm doing about 195-203 degrees (F). Any info would be helpful... Thanks :eek:

That's a great temp. I'm so slow that I tend to run 230ish on trails. I shut it down to cool at 250ish.

A 50-50 mix of standard coolant/distilled water boils at ~260 deg F. You are well within the comfort zone of the motor.

Excellent, thanks guys I was getting a little worried. I feel better now thanks

Anything below 240 is normal for a bike.

My vapor is set for yellow @ 210 and red @ 250. Seems to well for me.

Thanks for all the replies, that's the reason I wanted to know, my vapor says 200 is high so I thought maybe I was in trouble, then I realized that you can set the temperature range so 240 and 250 it is.

You guys talking about the coolant temp sensor on the Vapor?

I think he was asking .... how hot is too hot.

Its the coolant I was worried about, the motor doesn't get that hot but the coolant seems to rise pretty fast, also my header pipe gets hot to, not normal hot but really hot to where I can feel it in my leg. But the bike is running so good that I don't want to mess with anything unless I know what the problem is, any thoughts?

All normal.

Modern 4S race bikes like yours can run 900 degrees at the header and glow if left idling more than a minute. Even on my SM, I feel the heat mid leg from the Ti pipe due to the thin wall construction.

Cool thanks, glad there is nothing wrong with my baby haha. Thanks guys

So what's a good setting for the vapors coolant temp lights?

Right now mine is set at 230 for high and 250 for danger. So far everything is going good, havent hit 230 yet.

Perfect, thanks.
